Part Number: UCC2897A Other Parts Discussed in Thread: PMP22509 , CSD19537Q3 , TL431
Hello Power Team
we build a board for 5V,5A, using pmp22509 reference design schematic,
i tested this board at 24VDC input voltage and below observation
i)…
Sorry i didn't understand why it is not used for buck operation. In this link https://www.ti.com/tool/PMP22509 it is mentioned that the UCC2897A can be able to convert 18v-36v dc to 5v dc. what is this mean here? Can you please explain.
Hello Ahmet,
The TPS2376H is a very old IC (released 2006). We highly discourage this for new designs. This design was released before the IEEE802.3.at standard, that allowed for 25W on the PD. So we highly recommend using an IC released after this…
Hello Zhang,
TI has produced a Reference Design that suits your needs very nicely: PMP22509 . This design utilizes the UCC2897A in an active clamp forward topology to achieve 88.8% / 90.2% / 90.1% efficiency at 18Vin / 24Vin / 36Vin at 5A load. The…
